New Alkaline Papers

Penntech Papers, Inc. (White Plains, NY) announced that as of
June 1, it would be making its two top trade book grades to an
alkaline pH: Clarion Book Offset and Pennbook. They will meet or
exceed the ANSI standard for paper permanence, even after aging for
two days at 90°C and 50% RH.

Weyerhaeuser Paper Company (Wayne, PA) introduced its first
business paper this spring, a 24 lb. cut sheet product called First
Choice for Important Documents. It has a pH of about 8.0 and is
made at the Rothschild mill.

The National Library of Canada is keeping a list of Canadian
alkaline mills and papers, and the distributors who handle them, and
is giving it out to anyone who requests information on them. The
National Library's list is virtually identical to the one kept by
this Newsletter, but the advantage to Canadians is that it costs
less for a telephone call. Call Anna Lehn, Preservation Librarian,
613/996-7386. (The four companies are: Canadian Pacific Forest
Products, Island Paper Mills, Weyerhaeuser Canada, and Domtar. The
first three are 100%. alkaline.)

Grade Finders, Inc., will indicate in its new Fine Paper
Directory which papers are alkaline and woodfree, not only for mill
brands but for private brands too.
